Erectile dysfunction (ED) has been linked to obstructive sleep apnea (OSA). This study used computed tomography (CT) to identify cephalometric and upper airway anatomic features in patients with OSA that correlate with the presence of ED. In this prospective study, 20 CT cephalometric and upper airway measurements, most commonly associated with OSA, were analyzed in 53 age- and BMI-matched consecutive eligible subjects. Twenty-two were diagnosed with OSA and ED (OSA+/ED+), 17 with OSA without ED (OSA+/ED−), and 14 without OSA and ED (OSA−/ED−) serving as a control group. Although OSA+/ED+ did not differentiate significantly in CT measurements from OSA+/ED−, they showed more alterations when compared to OSA−/ED−, which included narrower bony oropharynx, longer soft palate and uvula (PNS-P), and narrower retropalatal and retrolingual airway diameter (p

Purpose To investigate the association between the clinical status of patients with metastatic bone disease and the type of bone metastases. Patients and methods 80 patients with skeletal metastases underwent both clinical and radiological assessments. Bone lesions were evaluated with computed tomography (CT), and patients were separated into three groups: lytic, mixed, sclerotic. Bone density of each lesion was measured in Hounsfield units (HU). Results Patients with osteolytic lesions had the highest mean pain score with 8.1 ± 2.2 points, the least mean scores for quality of life (QoL) and performance status (PS) with 31.4 ± 14.6 and 58.6 ± 9.7 points respectively, the highest percentage and mean opioid consumption (100% and 220.9 mg of oral daily morphine equivalent respectively), and the least mean bone density (116.3 ± 40.4 HU). On the contrary, the group with sclerotic metastases had the least mean pain score with 4.6 ± 1.3 points, the highest mean scores of QoL and PS (61.1 ± 15.5 and 66.6 ± 10 points respectively), the least percentage and mean opioid requirement (55.5% and 170.6 mg respectively), and the highest mean bone density (444 ± 86.6 HU). The differences between the three groups were statistically significant for all parameters evaluated, apart from performance status between the sclerotic and mixed groups. The correlation coefficients were statistically significant between all parameters investigated. Bone density had a strong negative correlation with pain. Conclusion Our results show a clear correlation between the type of bone metastases and the clinical status of patients. Patients with excessive bone resorption suffer the most, and may be given priority in treatment. CT proved to be a practical and efficient method to investigate and classify metastatic bone lesions.
